  1. In this work, a new dual triangulate bluff body vortex flowmeter was developed, the flux lower limit value of which lower by 50 % that of the old single bluff body vortex flowmeter. the linear correlation of the correlation between the velocity pressures of fluid disturbs wave and that of vortex precession in vortex precession flowmeter was brought to light, and a spectrum phase discrimination method based on fft to remove the effect of fluid pulsating interference on vortex precession flowmeter was advanced

    研製出比傳統單鈍體渦街流量計流量下限降低約50的新型雙鈍體渦街流量計；揭示出脈動流中旋進旋渦流量計流體振動特性，並在此基礎上提出基於fft相位判別的數字信號處理方法來消除流場脈動對旋進旋渦流量計的干擾的方法。
  2. Vortex precession flowmeter

    旋渦進動流量計
  3. There are two kinds of vortex type oscillatory flowmeter : vortex flowmeter and vortex precession flowmeter

    基於旋渦流體振蕩原理的流量計主要有兩種：渦街流量計和旋進旋渦流量計。
  4. The technique of fluid mechanics simulation and the technique of modern fluid mechanics experiment were applied to research on the fluid oscillation characteristics of vortex flowmeter and vortex precession flowmeter

    以流場模擬技術和實驗流體力學的相結合的方法，系統地研究了旋渦型流體振動流量計的流體振動特性。
